This application is a 371 of PCT/EP97/04902 filed Sep. 9, 1997.

DESCRIPTION

The present invention relates to novel substituted carbamoyltriazoles of the formula I

where:

R¹ is hydrogen, C₁-C₆-alkyl, C₁-C₆-haloalkyl, C₃-C₈-cycloalkyl, C₃-C₆-alkenyl or C₃-C₆-alkynyl;

R² is C₁-C₆-alkoxy or C₁-C₆-haloalkoxy or a radical listed under R¹; or

R¹ and R² together form a C₂-C₅-alkanediyl radical which may carry one to three substituents selected from the group consisting of halogen and C₁-C₆-alkyl and, in the case of a C₄-C₅-alkanediyl radical, a CH₂ group may be replaced by oxygen or a group NH or N-C₁-C₆-alkyl;

R³,R⁴ and R⁵ are each hydrogen, cyano, C₁-C₆-alkyl, C₁-C₆-haloalkyl, C₃-C₆-cycloalkyl, C₂-C₆-alkenyl, C₂-C₆-alkynyl, C₁-C₆-alkoxy, C₁-C₆-haloalkoxy, C₁-C₆-alkylthio, C₁-C₆-alkylcarbonyl, C₁-C₆-haloalkylcarbonyl, C₁-C₆-alkoxycarbonyl, phenyl or benzyl, where the last two substituents may be partially or fully halogenated and may carry one to three of the following groups:

nitro, cyano, C₁-C₄-alkyl, C₁-C₄-haloalkyl, C₁-C₄-alkoxy, C₁-C₄-haloalkoxy and C₁-C₄-alkoxycarbonyl;

A is an unsubstituted or substituted saturated or partially unsaturated five or six-membered heterocycle containing one to three hetero atoms selected from the group consisting of oxygen, sulfur and nitrogen;

n is 0, 1 or 2;

with the proviso that A is not 1,3-dioxolan-2-yl or 1,3-dioxan-2-yl;

and the agriculturally useful salts of I.

Furthermore, the invention relates to processes for preparing compounds of the formula I, to compositions comprising them and to their use for controlling harmful plants.

Carbamoyltriazoles are known from the literature, for example from EP-A 140 194, EP-A 422 369, U.S. Pat. No. 5,308,830, JP-A 07 053 529 and JP-A 61 178 930.

However, the herbicidal properties of the prior art compounds and the compatibility with crop plants are not fully satisfactory.

It is an object of the present invention to provide novel, in particular herbicidally active, compounds having improved properties and also novel intermediates, the triazoles of the formula II.

We have found that this object is achieved by the substituted carbamoyltriazoles of the formula I and their herbicidal activity and also by intermediates and processes for preparing the compounds I.

This invention further provides herbicidal compositions which comprise the compounds I and which have a very good herbicidal activity. It additionally provides processes for the preparation of these compositions and methods for controlling undesirable vegetation using the compounds I.

Depending on the substitution pattern, the compounds of the formula I can contain one or more chiral centers, in which case they exist in the form of enantiomer or diastereomer mixtures. This invention provides the pure enantiomers or diastereomers as well as their mixtures.

The compounds of the formula I may also be present in the form of their agriculturally useful salts, the kind of salt as a rule not being important. The salts of those cations or the acid addition salts of those acids are generally suitable whose cations or anions, respectively, do not interfere with the herbicidal activity of the compounds I. Suitable cations are in particular ions of the alkali metals, preferably sodium and potassium, of the alkaline earth metals, preferably calcium and magnesium, and of the transition metals, preferably manganese, copper, zinc and iron, and ammonium which, if desired, may carry one to four C₁-C₄-alkyl substituents and/or one phenyl or benzyl substituent, preferably diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, and furthermore phosphonium ions, sulfonium ions, preferably tri (C₁-C₄-alkyl)sulfonium, and sulfoxonium ions, preferably tri (C₁-C₄-alkyl) sulfoxonium.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogen sulfate, sulfate, dihydrogenphosphate, hydrogenphosphate, nitrate, hydrogencarbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate and the anions of C₁-C₄-alkanoic acids, preferably formate, acetate, propionate and butyrate.

The substituted carbamoyltriazoles of the formula I can be obtained in a variety of ways, for example by one of the processes below:

Process A

Reaction of a triazole of the formula II with a carbamoyl halide of the formula III

L¹ is halogen, preferably chlorine.

As a rule, the reaction is carried out in an inert organic solvent. Suitable inert organic solvents are, for example, aromatic hydrocarbons, such as benzene or toluene, halogenated hydrocarbons, such as methylene chloride, 1,2-dichloroethane or chlorobenzene, ethers, such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran or dioxane, ketones, such as acetone or methyl ethyl ketone, or polar solvents, such as dimethylformamide, diethylformamide or dimethyl sulfoxide, or mixtures thereof.

It may be advantageous to carry out the reaction in the presence of a base. Suitable bases are, inter alia, alkali metal alkoxides, in particular sodium methoxide or sodium ethoxide, alkali metal hydroxides, in particular sodium hydroxide or potassium hydroxide, alkali metal carbonates, in particular sodium carbonate or potassium carbonate, metal hydrides, such as sodium hydride, organic bases, for example amines, such as triethylamine, pyridine or N,N-dimethylaminopyridine, or mixtures thereof.

As a rule, the starting materials are employed in equimolar amounts. However, it may be advantageous to employ an excess of one or the other component.

The amount of the base is preferably 0.5 to two times the molar amount, based on the starting materials.

The reaction temperature is generally in the range from 0° C. to the boiling point of the reaction mixture.

Process B

Reaction of substituted carbamoyltriazoles of the formula I where n=0,

with oxidizing agents to give substituted carbamoyltriazoles of the formula I where n=1 or 2.

Suitable oxidizing agents are, inter alia, organic peroxides, such as m-chloroperbenzoic acid, peroxyacetic acid or trifluoroperoxyacetic acid, and inorganic peroxides, such as hydrogen peroxide or sodium periodate.

It may also be advantageous to add catalysts, such as tungstates.

Depending on the oxidizing agent, suitable solvents are aromatic hydrocarbons, such as benzene or toluene, halogenated hydrocarbons, such as methylene chloride, chloroform, 1,2-dichloroethane or chlorobenzene, organic acids, such as acetic acid, propionic acid or trifluoroacetic acid, or mixtures thereof.

The oxidizing agent can be employed in an equimolar amount, based on the starting material; although it may be advantageous to use an excess of up to 10 molar equivalents. Generally, the oxidation catalyst is employed in a ratio of 1 to 20 mol %, based on the starting material.

The reaction temperature is usually in the range of from 0° C. to the boiling point of the reaction mixture.

The particularly preferred embodiments of the triazoles of the formula II as regards the variables R¹ to R⁵ correspond to those of the substituted carbamoyltriazoles of the formula I.

The preparation of the compounds of the formula II where n=0 is carried out for example by reacting a mercaptotriazole of the formula IV

with a compound of the formula V,

where L² is a nucleophilically displaceable leaving group, such as halogen, for example chlorine or bromine, C₁-C₆-alkylsulfonyloxy, for example mesylate, C₁-C₆-haloalkylsulfonyloxy, for example triflate, or arylsulfonyloxy, for example tosylate.

These compounds are synthesized similarly to the conditions described under Process A.

Work-up of the reaction mixtures is generally carried out by methods known per se, for example by removing the solvent, partitioning the residue in a mixture of water and organic solvent and work-up of the organic phase to afford the product.

PREPARATION EXAMPLES Example 1 1-Diethylcarbamoyl-3-(tetrahydropyran-2-yl)-methylsulfonyl-1,2,4-triazole (Compound 2.02)

a) Tetrahydropyran-2-ylmethyl methanesulfonate

In 200 ml of toluene, 23.2 g (200 mmol) of tetrahydropyran-2-ylmethanol were admixed with 27.5 g (240 mmol) of methanesulfonyl chloride. At 10° C., 24.3 g (240 mmol) of triethylamine were then added dropwise, and stirring was continued for 2 hours at room temperature. 200 ml of methyl tert-butyl ether and 200 ml of water were then added to the mixture and the organic phase was separated off, washed with 200 ml of water and dried. Removal of the solvent under reduced presure gave 33.7 g (87% of theory) of a clear oil. (¹H-NMR (CDCl₃; δ in ppm): 4.20 (d,2H); 4.05 (dd,1H); 3.60 (m,1H); 3.45 (m,1H); 3.1 (s,3H); 1.95 (m,1H); 1.45 (m,5H))

5.0 g (17 mmol) of 1-diethylcarbamoyl-3-(tetrahydropyran-2-yl)methylthio-1-2,4-triazole (step c) were dissolved in 100 ml of glacial acetic acid and admixed with a spatula-tipful of sodium tungstate. At 50° C., 4.8 g (42 mmol) of hydrogen peroxide (30% strength solution in water) were then added dropwise and the mixture was heated under reflux for 2 hours. After cooling, 100 ml of water and 100 ml of dichloromethane were added to the reaction mixture and the organic phase was washed with sodium dithionite solution and then with sodium bicarbonate solution, and dried. The solution was concentrated and the residue was digested with a little diethyl ether and filtered off under suction. 3.0 g (50% of theory) of a white crystalline powder (melting point 122° C.) were obtained.

The compounds of the formula I and their agriculturally useful salts are suitable as herbicides and/or as bioregulators, both in the form of isomer mixtures and in the form of the pure isomers. The herbicidal compositions comprising compounds of the formula I are capable of controlling vegetation on non-crop areas very efficiently, especially at high rates of application. In crops such as wheat, rice, maize, soya and cotton, they act against broad-leaved weeds and grass weeds without causing any significant damage to the crop plants. This effect is observed mainly at low rates of application.

Depending on the application method employed, the compounds of the formula I, or herbicidal compositions comprising them, can additionally be employed in a further number of crop plants for eliminating undesirable plants. Examples of suitable crops are the following:

Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N.rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticum durum, Vicia faba, Vitis vinifera and Zea mays.

In addition, the compounds of the formula I can also be used in crops which tolerate the action of herbicides owing to breeding including genetic engineering methods.

The compounds of the formula I, or the herbicidal compositions comprising them, can be used for example in the form of directly sprayable aqueous solutions, powders, suspensions, also highly concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading or granules by means of spraying, atomizing, dusting, spreading or watering. The use forms depend on the intended purposes; in any case, they should ensure the finest possible distribution of the active ingredients according to the invention.

Suitable inert additives are essentially: mineral oil fractions of medium to high boiling point, such as kerosine or diesel oil, further coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, eg. paraffin, tetrahydronaphthalene, alkylated naphthalenes or their derivatives, alkylated benzenes or their derivatives, alcohols, such as methanol, ethanol, propanol, butanol, cyclohexanol, ketones, such as cyclohexanone, or strongly polar solvents, eg. amines, such as N-methylpyrrolidone, or water.

Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, these concentrates being suitable for dilution with water.

Suitable surfactants (adjuvants) are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, eg. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, of alkyl- and alkylarylsulfonates, of alkyl, lauryl ether and fatty alcohol sulfates, and the salts of sulfated hexa-, hepta- and octadecanols and of fatty alcohol glycol ether, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of naphthalenesulfonic acids, with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl polyglycol ethers, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methyl cellulose.

Powders, materials for spreading and dusts can be prepared by mixing or grinding the active substances with a solid carrier.

Granules, eg. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Solid carriers are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders, or other solid carriers.

The concentrations of the active ingredients of the formula I in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of at least one active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The following Formulation Examples illustrate the preparation of such preparations:

I. 20 parts by weight of the compound No. 2.02 are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide and 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide and 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.

II. 20 parts by weight of the compound No. 2.04 are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide and 1 mol of isooctylphenol and 10 parts by weight of the adduct of 40 mol of ethylene oxide and 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.

III. 20 parts by weight of the active ingredient No. 2.06 are dissolved in a mixture composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 280° C. and 10 parts by weight of the adduct of 40 mol of ethylene oxide and 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.

IV. 20 parts by weight of the active ingredient No. 2.11 are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalene-α-sulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel and the mixture is ground in a hammermill. Finely distributing the mixture in 20,000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active ingredient.

V. 3 parts by weight of the active ingredient No. 2.14 are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of the active ingredient.

VI. 20 parts by weight of the active ingredient No. 2.02 are mixed intimately with 2 parts by weight of calcium dodecylbenzenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.

VII. 1 part by weight of the compound 2.16 is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.

VIII. 1 part by weight of the compound 2.26 is dissolved in a mixture composed of 80 parts by weight of cyclohexanone and 20 parts by weight of Wettol® EM 31 (=nonionic emulsifier based on ethoxylated castor oil; BASF AG). This gives a stable emulsion concentrate.

The active ingredients of the formula I or the herbicidal compositions can be applied pre- or post-emergence. If the active ingredients are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of spraying apparatus, in such a way that they come into as little contact as possible, if any, with the leaves of the sensitive crop plants, while the active ingredients reach the leaves of undesirable plants which grow underneath, or the exposed soil surface (post-directed, lay-by).

Depending on the intended purpose, the season, the target plants and the growth stage, the rates of application of active ingredient of the formula I are from 0.001 to 3.0, preferably 0.01 to 1.0, kg of active substance (a.s.) per ha.

To widen the spectrum of action and to achieve synergistic effects, the substituted carbamoyl derivatives of the formula I can be mixed with a large number of representatives of other groups of herbicidal or growth-regulating active ingredients and applied jointly. Suitable components for mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, (het)aryloxyalkanoic acids, and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(het)aroyl-1,3-cyclohexanediones, hetaryl aryl ketones, benzylisoxazolidinones, meta-CF₃-phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexane-1,3-dione derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- or hetaryloxyphenoxypropionic esters, phenylacetic acid and its derivatives, 2-phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.

Furthermore, it may be advantageous to employ the compounds of the formula I, on their own or in combination with other herbicides, also in a mixture with other crop protection agents, for example pesticides or agents for controlling phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions which are employed for treating nutritional and trace element deficiencies. Nonphytotoxic oils and oil concentrates may also be added.

Use Examples

The herbicidal activity of the substituted carbamoyl derivatives of the formula I was demonstrated by greenhouse experiments:

The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

In the case of pre-emergence treatment, the active ingredients, which were suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transluscent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants unless this was adversely affected by the active ingredients. The rate of application for the pre-emergence treatment was 3.0 kg of a.s./ha.

For the post-emergence treatment, the test plants were first grown to a plant height of from 3 to 15 cm, depending on the plant habit, and only then treated with the active ingredients which had been suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment.

Depending on the species, the plants were kept at from 10-25° C. or 20-35° C. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

Evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial parts, and 0 means no damage or normal course of growth.

The plants used in the greenhouse experiments belong to the following species:

Scientific Name Common Name Echinochloa crus-galli barnyardgrass Lolium multiflorum annual ryegrass

Using the pre-emergence method, the compounds 2.02 and 2.04 showed, at application rates of 3.0 kg/ha a.s., very good activity against the abovementioned harmful grasses.
